Solution

 

 

At both store and head

IDEALLY, the serial ports and software along the entire polling path from ECR or POS station to the

office locations:

head office polling software should be set the same. These include:

 

• any software in the ECR or POS station that permits polling access

 

• the ECR or POS station’s polling serial port

 

• the ST Plus’s serial port

 

• the “Modem” port on the HQ Plus

 

• the serial port on the host PC that is connected to the “Modem” port on the HQ Plus

 

• the polling software on the host PC at the head office

 

 

HQ Basic does not show active HQ Plus to ST Plus connections

At the head office:

Ensure that HQ Basic is properly installed on its host PC. This PC might or might not be the same PC

 

that is hosting the polling software, but if these two applications are sharing one host PC then

 

ensure that the joint host PC has two distinct serial ports, one for each application to use.

 

 

 

Ensure that HQ Basic is configured to address the same serial port that is connected to the

 

“Console” port of the HQ Plus.

 

 

 

Ensure that the serial port that HQ Basic is addressing is connected to the “Console” port of the HQ

 

Plus using a straight-through serial cable.

 

 

HQ Remote Console and HQ Remote Poller initial setup

At the head office and store

Ensure that a working HQ-ST Link setup is already in place before attempting to add an HQ Remote

locations:

Console or HQ Remote Poller to the mix. Polling software at the head office should be able to

 

successfully poll an ECR or POS station at a remote store location, to verify connectivity.

 

 

HQ Remote Console does not show ST Plus connections on the HQ Plus

At the head office location:

Ensure that HQ Basic running at the head office has been configured to permit remote accesses.

 

 

At the location of the HQ

Ensure that HQ Basic is properly installed on the host PC at the remote location. This PC might or

Remote Console:

might not be the same PC that is hosting an HQ Remote Poller, but if these two devices are sharing

 

one host PC then that PC needs two distinct serial ports, one for each device to use.

 

 

 

Ensure that HQ Basic at the remote location is configured to address the same serial port that is

 

connected to the serial port of the HQ Remote Console.

 

 

 

Ensure that the serial port that HQ Basic is addressing is connected to the serial port of the HQ

 

Remote Console using a straight-through serial cable.

 

 

 

Ensure power is supplied to the HQ Remote Console.

 

 

 

Check that the LAN to which the HQ Remote Console is connected has access to the Internet.

 

 

 

Check that the HQ Remote Console is connected to the LAN with a Cat 5 UTP cable, with an RJ-45

 

connector.

 

 

HQ Remote Poller does not poll the ECR/POS station

At the head office location:

Ensure that HQ Basic running at the head office has been configured to permit remote accesses.

 

 

At the location of the HQ

Ensure that the polling software is properly installed on the host PC at the remote location. This PC

Remote Poller:

might or might not be the same PC that is hosting an HQ Remote Console, but if these two devices

 

are sharing one host PC then that PC needs two distinct serial ports, one for each device to use.

 

 

 

Ensure that the polling software at the remote location is configured to address the same serial port

 

that is connected to the serial port of the ECR/POS station.

 

 

 

Ensure that the serial port that the polling software is addressing is connected to the serial port of

 

the HQ Remote Poller using a straight-through serial cable.

 

 

 

Ensure power is supplied to the HQ Remote Poller.

 

 

 

Check that the LAN to which the HQ Remote Poller is connected has access to the Internet.

 

 

 

Check that the HQ Remote Poller is connected to the LAN with a Cat 5 UTP cable, with an RJ-45

 

connector.

 

 

NOTE: An operating HQ Remote Poller setup is in fact an exercise of most aspects of the HQ-ST Link system. This is because a poll directed from an HQ Remote Poller must successfully pass from the location of the HQ Remote Poller, over the Internet to the HQ Plus running at the head office, out to the Internet again and over to the ST Plus at its store location, through to the ECR or POS station being polled, then back to the ST Plus again and out to the Internet again and over to the HQ Plus, then out to the Internet yet again and back to the HQ Remote Poller, then finally to the remote host PC . This will only happen when all aspects of the full HQ-ST system are working (with the exception of the HQ Remote Console).
